When you have knee pain, you just want it to go away so you can walk without having to limp or wince with every step. And a small, randomized trial published online Jan. 12, 2021, by Annals of Internal Medicine found that one type of shoe might be best for the job. Researchers took 164 people ages 50 or older with moderate or severe knee arthritis and randomly assigned half of the group to wear stable, supportive shoes with thick soles that didn't bend much. The other half was assigned flat shoes with thin, flexible soles, which are believed by some to provide a benefit by allowing more natural movement of the leg and foot. Both groups wore their assigned shoes for six hours per day and took part in activities such as walking during that time. After six months, 58% of people in the stable, supportive shoe group reported a reduction in knee pain while walking, compared with 40% of people reporting pain reduction after wearing the flat, flexible shoes. In both groups, the pain reduction probably was a benefit of regular walking. The people wearing flexible shoes were also twice as likely to develop ankle or foot pain, compared with those wearing sturdy shoes. So if you have knee pain, keep walking — in sturdy shoes.

Exciting benefits of walking for heart health, including lower risk of heart attack and stroke

Why should you start walking for heart health? Walking doesn't get the respect it deserves, either for its health benefits, its value for transportation, or its role in recreation.

Aerobics, walking and health

Ever since the 1970s, the aerobic doctrine has dominated the discussion of exercise and health. In a scientific update of your high school coach's slogan "no pain, no gain," the doctrine holds that the benefits of exercise depend on working hard enough to boost your heart rate to 70% to 85% of its maximum, sustaining that effort continuously for 20 to 60 minutes, and repeating the workout at least three times a week.

Your heart, like any other muscle, can weaken over time, especially if you are sedentary. As you age and become less active, the muscle in your heart's left ventricle — the chamber that pumps oxygen-rich blood back out to the body — becomes stiffer.

"This change in the heart muscle, coupled with simultaneous stiffening of the body's arteries that leads to high blood pressure, begins a harmful cardiovascular aging cycle," says Dr. Aaron Baggish, director of the Cardiovascular Performance Program at Harvard-affiliated Massachusetts General Hospital. "Without intervention, this sets the stage for heart failure later in life."

Men may avoid activity because of their knee pain, but movement is exactly what they need.

It is perhaps the ultimate exercise catch-22: it's hard to move with knee osteoarthritis, but moving helps relieve osteoarthritis knee pain.

More than 30 million Americans have osteoarthritis, the most common kind of arthritis. While osteoarthritis can affect the hips, lower back, neck, and fingers, it occurs most often in the knees. In fact, an estimated 10% of men ages 60 and older have symptoms of knee osteoarthritis.

Yoga is a gentle practice that is ideal for maintaining back strength and flexibility. It's also one of the more effective tools for helping reduce low back pain, the most common source of pain and disability among older adults.

"Yoga helps strengthen and stretch back muscles that might be tight, which improves mobility," says Dr. Lauren Elson, medical editor of the Harvard Special Health Report An Introduction to Yoga (www.health.harvard.edu/yo).

A good one can provide motivation and customized advice on a safe, effective, and well-rounded exercise routine.

Exercise is one of the pillars of heart disease prevention. But at some point, you may need help shoring up your workout habits. Maybe you exercise only in fits and starts, without sticking to a regular routine. Or perhaps you're in a rut, doing the same old 30-minute trudge on the treadmill every day.

Another possibility: You have a health condition (such as high blood pressure or arthritis) or another physical problem (an old knee or back injury, for example) that makes you hesitant to exercise. For all of these reasons and more, hiring a personal trainer can be a sound investment.

Lifestyle changes — along with other proven therapies — can help improve these often-overlapping conditions.

Everyone goes through periods of feeling gloomy, irritable, or listless at least once in a while. And these emotions are perfectly normal after a diagnosis of a serious health problem such as heart disease. But if those unpleasant feelings drag on for weeks and gradually erase your sense of well-being, you may have depression.

Over a lifetime, about one in five Americans is affected by depression. But the risk of depression in people who've had a heart attack is three times as high as the risk among the general population.
